(Cl. 4-2) ABSTRACT F THE DISCLOSURE A support arrangement formed by a frame structure for the piping and equipment of a sanitary installation in a housing unit. The main discharge conduit of the installation forms the principal load-bearing member of the frame. A pair of spaced support members arranged in aligned parallel relationship are secured to and extend generally perpendicularly from the main discharge conduit forming the horizontal portions of the frame. The frame is completed by an upright member secured and extending between the upper and lower support members and spaced from the main discharge conduit. In one arrangement of the support frame, both of the support members are pipes attached to and in communication with the main discharge conduit, in this embodiment the upright member is also a pipe providing communication between the lower` and upper support members. Another embodiment utilizes a bar member for the upper support member and a discharge pipe for the lower member. The piping and certain of the equipment in the sanitary installation are supported on the frame.

The invention relates to sanitary installations that provide a rigid framework of plumbing and can be quickly installed as a unit.

It is known to install these sanitary installations either in a previously manufactured section of a Wall or in a framework, which latter is then concealed by a wall. In all of these known types of construction, the wall section or framework provided with the sanitary installation is installed during the erection of the building, so -that the installation progresses only bit by bit as the building is brought to completion.

The invention possesses the great advantage that the entire sanitary installation can be set up in the nished building as the last step in construction, Without using a framework or load bearing walls. Extra work, such as tiling, plastering, and the closing up of holes in the wall, is rendered unnecessary. Thus, the setting up of the installation and its connection to the main conduit, and the mounting and connection of the various pieces of sanitary equipment can be accomplished in a single, unbroken step.

An object of the invention is sanitary installations that can be installed in a single step in a building, ithat is in its last stage of construction.

Another object of the invention is sanitary installations that provide a rigid, unitary framework for holding and supporting the sanitary equipment, such as a toilet, lavatory and sink.

These and further objects of the invention will be apparent from the following detailed description, with reference to the accompanying drawings, wherein:

FIGURES l and 2 illustrate two embodiments of the invention in plan view;

FIGURE 3 is a plan view of the form of FIGURE 1 or 2, as installed in a kitchen;

FIGURE 4 is a top view of either embodiment of the invention, with the sanitary equipment installed in the bathroom and kitchen.

3,381,313 Patented May 7, 1968 vIce Referring to FIGURE l, the invention has a rst standpipe 1 for hot water, a second standpipe 2 for cold water, a main discharge pipe 3 (of which only a section is shown) for the waste water of the entire plumbing installation, and a fourth pipe 4 for circulating hot water for. heating the building. As shown in the figures, standpipes 1, 2 and 4 are provided with insulation 5 and supported by a bracket 6. A horizontal support 7, in the form of a profiled bar, is secured at one end to the main discharge pipe 3 by means of the bracket 6. The pipe 3 serves as ,the principal load bearing member for the entire installation.

To the standpipes 1 and 2 are connected, respectively, a distribution pipe 8 that extends parallel to the support 7 and has three branches 9, 10 and 11, and a distribution pipe 12 provided with four branches 13, 14, 15 and 16. All of the branch pipes can be suitably threaded on their ends for connection to supply pipes for the sanitary equipment. A mixing faucet 17 for a lavatory 18 is connected to the branches l9 and 14, one 19 for a bathtub 20 to branches 11 and 16, and one (not shown) for a kitchen sink 21 (FIGURE 3) connected to branches 10 and 15.

Additional discharge pipes 22 and 23 are connected to 4the main discharge pipe 3. The larger pipe 22 is connected to the outlet 24 of a toilet 25, whereas the smaller pipe 23 is connected by a first branch 26 to the sink 21 and through a pipe 27 to the trap 28 of the lavatory 18. IIn addition, the end 29 of pipe 23 is connected to the drain 30, as well as by pipe 31 to the overflow 32 of the bathtub 20.

Both distribution pipes 8 and 12 for hot and cold water are held, through their branches 11 and 16, by the support 7, which is braced by the discharge pipe 23 through a bar 33 that rests on its one end 33 on the oor 45 and acts thereby to support pipe 23.

The pipes 3 and 23 together with the support 7 and bar 33 constitute a substantially rectangular frame 43 which connects together all of the horizontal pipes and the anchoring points for the sanitary equipment (sink, toilet, etc.) into aunit.

A plate 34, serving to secure the toilet 25, is anchored by a bar SI5-itself secured to the bracket 7 at its upper endand the toilet discharge pipe 22, which latter is supported by a bar 36 joined to the pipe 23. The plate 34, through discharge pipe 37, also serves to support the tank 3S, which is also braced by the support 7. The branch pipe 13 connects the tank 38 to the cold water distribution conduit 12. For anchoring the toilet 25, the plate 34 has tapholes 39. Two threaded sockets 40, welded to the support 7, serve to hold the lavoratory 18.

Two shuto valves 41 and 42, respectively connected in lines 8 and 12 near the standpipes 1 and 2, can cut off the flow of water should, for example, one of the mixing faucets become defective and require replacement.

FIGURE 2 illustrates a second embodiment of the invention, wherein the horizontal support 7a (which bears the tensile forces) of the frame 44 consists of a pipe, which, through the vertical main discharge pipe 3 and a connecting pipe 43 (replacing the support bar 33), is connected to the horizontal discharge pipe 23, located near the floor 45 and bearing the thrust forces. The one end of pipe support 7a is connected to the main discharge conduit 3.

The above form of the invention realizes the important advantage that all of the drains of the sanitary equipment, such as the bathtub, the sink, and the lavatory, are automatically ventilated, whereby the gurgling noise that accompanies the discharge of a liquid is eliminated. That is, the air, rather than mixing with the draining Water and so causing a noisy turbulence, is permitted to escape through pipes 43 and 46 to the discharge pipe 3.

Moreover, the compression and tenon members 23 and 7a and the pipe 43 connecting them can be of the same pipe material having the same cross section.

In accordance with the invention, this embodiment can offer the further advantage that the connecting pipe 43 can be designed to be used directly for carrying the drain water of the lavatory and/ or the kitchen sink.

Further in accordance with this form of the invention, the branch pipes 11 and 16 are held by a plate 46 rigidly connected to the support 7a. As in the previous form, two threaded sockets 40 for anchoring the lavatory 18 are welded on the support. In other respects the form of FIG- URE 2 corresponds to that of FIGURE 1, like elements being designated by like reference numerals.

By eliminating the vertical ventilation pipe 43, the discharge pipe 26 can be extended (as suggested by the dotted lines) to connect with the pipe support 7a (while remaining connected to the sink), whereby the pipes 3, 7a, 23 and 26 form a rigid, load bearing frame. In this form, also, the gurgling noise is eliminated, because the air can escape by way of conduits 26 and 7a to the pipe 3.

The horizontal support 7a and either the pipe 43 or 26 permit a secondary Ventilation, which can be used in every installation.

As seen in either FIGURE 1 or 2, the sanitary installation is arranged on one side of a wall 47 that separates the bathroom from the kitchen. In the two figures the installation is shown mounted in the kitchen. The wall includes an opening 52 in which a medicine cabinet for the bathroom can be mounted, closing the opening. The pipes 22 and 37, 9 and 14 and 27, 11 and 16 and 29 are led through the wall 47 through suitable openings. Thus, the installation is connected to the wall 47, which, as it were, is squeezed between the sanitary equipment and its anchoring points.

During installation the plumbing simply can be moved towards the wall provided with the openings for the pipes and the pipes 1, 2, 3 and 4 allowed to pass through the kitchen floor by means of an opening 49, which latter is then filled with concrete to provide an absolutely firm support for the main discharge pipe 3, which acts as a pillar. Thus installed, the pipe 3 is capable of supportingV the load conveyed to it through the frame 43 (or 44) from the sanitary equipment.

As should be immediately apparent, the installation of the arrangement of the invention can be deferred until the last work is done on the building. In contrast to what has been the practice until now: of having to install the pipes and certain other pieces of plumbing during the early stages of construction, whereas the sanitary equipment and other parts could only be installed and connected in the finishing stages of construction, the whole arrangement of the invention can be installed at once.

As apparent from FIGURES 3 and 4, the installation, located in the kitchen, is entirely covered by the kitchen equipment. The standpipes 1 and 2, discharge pipe 3, and pipe 4 for central hot water heating are located in a broom closet 50, through which the shutoff valves 41 and 42 can be reached. A refrigerator 51 hides the toilet tank 38, the supply pipe 37 connecting the tank 38 to the toilet 25, and the discharge pipe 22 connecting the toilet to the main discharge pipe 3. Next to the drawers 52 (FIGURE 3) are successively located the sink 21 and a range 53. A kitchen cabinet 54 having three doors is located above the sink and range.

The standpipes 1, 2, 3 and 4 on each oor of a house can be extended by additional sections 1, 2', 3 and 4', as apparent from FIGURE 3, wherein the additional sections are shown in dotted line, whereas the pipes 1, 2, 3 and 4 are shown in dashed line. Thanks to this construction the sanitary installation of the invention is suitable for buildings of any height, simply by employing as many additional sections 1', 2', 3 and 4 as required by the number of floors.

The necessary electrical elements are installed with the sanitary installation of the invention. The wall sockets for the range, refrigerator, household appliances, and electric razor are mounted on individual members for immediate installation. The fuse box SS (FIGURE 3) for the entire living quarters is installed in the broom closet in accordance with regulations. Illumination for the bathroom and kitchen is provided in a similar manner by individual elements ready for installation.
